Abstract: Devices for maneuvering helicopters on a ship's deck ABSTRACT OF THE DISCLOSURE          The invention relates to devices for maneuvering helicopters on the deck of a ship. According to the invention, the helicopter, whose landing gear comprises at least one swivelling wheel, is maneuvered between a take-off and landing area and a garage area on the deck of a ship with the aid of a guide carriage, moving in a guide rail and connected to a fitting on the helicopter by a telescopic rod or a cable, as well as a guide bar engaged by a roller in the rail and hooked by a fork joint on the axle of the swivelling wheels of the helicopter.          When the helicopter is displaced towards the garage area by traction on a towing cable hooked at the front of the helicopter on the rear of which is hooked a retaining cable maintained tensioned, the helicopter automatically and progressively aligns itself on the axis of the rail due to the guide bar. The invention is more particularly applicable to flight decks of ships, platforms, etc...

Abstract: ABSTRACT OF THE DISCLOSURE           A high power lighting device comprises a low voltage lamp which is driven from a mains supply via a toroidal transformer.  The toroidal transformer is housed radially outside of the reflector of the low voltage lamp in an annular chamber defined by a portion of a housing and by a partition wall.  The partition wall is spaced from  the  low voltage lamp and from the toroidal transformer so as to form two coaxial airflow channels. Heat radiated from the low voltage lamp is picked up by the partition wall and air entering through suitably disposed openings at the front side of the lighting device flows through the two air channels and over both sides of the partition wall,  and leaves the housing through openings adjacent the threaded base.  The threaded base and the shape of the lighting device make it possible for the lighting device to be screwed into normal threaded lamp sockets used for pressed glass type lamps.

Abstract: EQUALIZER NETWORKS AND METHODS OF DEVELOPING SCALING COEFFICIENTS THEREFOR            Abstract of the Disclosure An adjustable equalizer network comprises a series chain of N all pass amplifier stages driving M minimum phase shift transversal filters connected to a final summing circuit that includes means to adjust each filter output to obtain a ripple free predetermined frequency response over a given frequency range.  Each filter includes N+1 scaling circuits connected to an intermediate summing circuit; the scaling circuits have scaling coefficients, of magnitude and sign determined by Fourier analysis and an appropriate truncation function, such that the filter has a pass band representative of one of M contiguous bands conjointly encom-passing the frequency range.  The adjustable equalizer, once adjusted for a desired frequency response, may be supplied with a DC reference input and used to determine the contri-bution (magnitude and sign) to the frequency response from each tap on the all pass chain, thus developing a set of N+1 scaling coefficients for a simplified equalizer network, com-prising the all pass chain with just one set of N+1 scaling circuits, that duplicates the response characteristic of the more complex adjustable equalizer.  Some embodiments incor-porate digital programming and control of the frequency response characteristic.

Abstract: ABSTRACT Reversing mechanism, particularly for semi-reversible ploughs, where the reversing mechanism includes hydraulic reversing cylinders (10, 11). The reversing mecha-nism, or device (5) to be reversed, includes a lifting arm (8) which at its one end is rotatably supported at a point (9) which the reversing mechanism turns about, and which at its other end is fastened to the device (5) to be reversed. The reversing cylinders (10, 11) have approximately the same volume and approxi-mately the same length of stroke and are affixed symmetrically to the lifting arm (8). The piston rods of the reversing cylinders (10, 11) are rotatably attached (15, 19) with one end of a pressure arm (17, 18) whose other end is rotatably fixed to the point (9) about which the reversing mechanism rotates. Each reversing cylinder (10, 11) is single-acting and arranged to turn the lifting arm (8) approxi-mately 110 degrees from horizontal position before the reversing cylinder (10, 11 ) has attained full length of stroke and the piston rod of the non-activated reversing cylinder (11, 10) is brought to abut against the abutment screw (21, 16) and brake the remainder of the reversing operation, which takes place with the aid of gravity. To identical double-acting hydraulic steering cylinders (24,25) are connected in parallel with the reversing cylinders (10, 11) and are thusarranged automatically to adjust, for example, the back wheel (4) of a semi-rever-sible plough when the reversing mechanism is activated.
